The code in
Listing 1 begins by declaring and
initializing variables named
velocity and
distance .
Note that the units are shown in the comments. I recommend that you always dothat in order to keep the units straight.

Perform the arithmetic

Then
Listing 1 declares a variable named
time and sets its value equal to
distance divided by
velocity . Once again, note the treatment of the units in the
comments, showing that the units for the result of the division are hours.

Display the results

Finally,
Listing 1 calls the
document.write method
several times in succession to display the results shown in
Figure 1 .

An exercise on average velocity

A hockey puck is struck by a player causing it to travel northeast at a uniform velocity of 50 feet
per second for 15 feet, at which point it is struck by another player.

When
struck by the second player, the direction of motion is changed to northwest witha uniform velocity of 60 feet per second.

It is stopped by a third player after
traveling 20 feet in the northwest direction.

What is the time required for the puck to complete each leg of its
journey?

What is the average velocity of the puck from the start to the end of its journey?

fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?

Damian

That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

what is the Synthesis, properties,and applications of carbon nano chemistry

Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
